Referring to the drawings, a casing 10 is shown. While this casing mightbe made in various forms, in the embodiment of the invention hereillustrated, said casing is shown to be generally parallelepiped in formhaving a front wall 10a, 2. front cover 10b, a top cover 100, sides Meand 10), a bottom 10g and a back wall 1%. Said cover 1012 has a handle10b. An offset portion 10m is provided about the upper side and frontedge portions of member 10 to provide a stop for cover 10c and to enablethe Wall 1012 and the front of cover 10c to be in flush position whensaid cover is closed. Said member 10 is here shown to have chambers 10:and 10f. Said chamber ltli has a bottom 10k therein. Said casing 10 isprovided with a handle 11 which is secured to said upper cover 100 byrivets 12. Said cover 100 is hingedly secured to casing 10 by a hinge13. Cover 10b is hingedly secured to casing 10 by a hinge 14. Saidcasing 10 may be made of any suitable material and preferably may bemade of sheet metal material. Secured to the upper portion of side 10aare guide members 15 which have a lower portion secured to said side asby welding, and have upper offset portions 15a forming guides. Saidmembers 15 are disposed in spaced pairs adjacent either end portion ofside 10a. Disposed in said guide portions 15a and movable therein is abar 17. Said bar is disclosed here as being made of sheet materialgenerally rectangular in cross section and extending for the greaterlength of said side 10a. Spaced members 18 are secured to side 10a toform a lower edge support and guide for said member 17. Said members 18are here shown to be nutted bolts secured to said side 10a. Said bar 17has a member secured to the mid-portion thereof being U-shaped inhorizontal section and forming a keeper. A look 20 is provided. Saidlock is secured to the mid-portion of said side 10a and is disposedslightly below the lower edge portion of said bar 17. Said lock 20 has arevolving barrel 20:: disposed therein, and secured to the inner endportion of said barrel 20a is a cam 20b. Said cam is rigidly secured tosaid barrel. Said lock is held in position on said side ltln by a locknut 20c. Said lock nut 20c has small spaced lugs 20d secured thereto tolimit the rotatable movement of said cam 20b. Said cam 20b is adapted tobe disposed in said keeper 17a.

Secured to said member 17 are spaced members 25 and 26. Said members 25and 26 may be secured to member 17 in any suitable manner, such as bywelding. Said members 25 and 26 respectively have right-angled upper endportions 25a and 26a. Thus members 25 and 26 form latch members. Securedto cover 100 are members 27 and 28. Said members 27 and 28 have lowerend portions forming loops 27a and 28a and said loops are generallyrectangular in vertical section and may be made of any suitablematerial, such as straps of sheet metal. When said cover 100 is inclosed position, said members 27a and 28a are disposed on the innerupper edge portion of said side 10a. Said members 25a and 26:: areadapted respectively to be disposed in said members 27a and 28a. Saidmembers 15 serve to limit the longitudinal movement of said bar 17.

Pivotally secured to the lower end portions of members 25 and 26respectively are members 30 and 31. Said members 30 and 31 are securedto said members 25 and 26 respectively by pivots 33. Said members 30 and31 form latch members, being linked with latch members 25 and 26 and areoperable therewith.

Secured to wall i adjacent the bottom 10k are members 37 and 38 havingoffset portions 37a and 38a .respectively forming guides. In alignmentwith said members 37 and 38 and disposed through said bottom 10?: areslotted openings 39 and 40.

Secured to the upper edge portion of cover 10!; and in alignment withopenings 39 and 4b are members 42 and 43. Members 42 and 43 respectivelyhave upper offset portions 42a and 43a. Said members 42 and 43 may besecured to said cover 10b in any suitable manner, as by welding.

In the operation of applicants device, the member 17 will be movedendwise by turning key 21 in lock 20. In the embodiment of the inventionhere illustrated, said key is turned clockwise, said bar 17 will move tothe right of said casing 10 and latch members 25a and Zea will becomedisengaged from the keepers 27 and 28. Thus the cover 100 is unlockedand may be lifted upwardly. As part of the same operation abovedescribed, when said bar 17 is moved to the right, latch members 33 and3.1 will be drawn upwardly through slots 39 and 4t) and will bedisengaged from keepers 42 and 43. Thus cover 10b will become unlockedand may be opened outwardly. The longitudinal movement of bar 17 islimited by the spaced members and also the lugs d on lock nut 20c. Saidmember 17 moves in channels formed by portions 15a of said members 15and is also supported by guide members 18.

When it is desired to lock casing 10, said covers 19c and 10b will beplaced in closed position and the key 21 will be turnedcounter-clockwise. As key 21 is turned, the revolving barrel 20a and thecam 26b will be turned. Said cam engages keeper 17a and thus movesmember 17 to the left. Latch members a and 2641 will then engage keepers27 and 28. Simultaneously with the above operation, the link latchmembers 39 and 31 will be guided by members 37 and 38 through openings39 and 40 and into keepers 42 and 43. Thus the cover 100 is lockedagainst upward movement and the cover 10b is locked against any outwardmovement.

Thus it is seen that I have provided a locking device of very simple andefiicient construction which is adapted to lock or unlock a plurality ofcovers in a casing with said covers opening in different planes.Applicants device has been fully tested in operation and has proved tobe very successful.
